Port It is a notion with several uses. In the computing , the term is used to name a connection class that makes it possible to send and receive information. USB , meanwhile, is the acronym corresponding to Universal Serial Bus , an interface that allows the connection of peripherals to various devices, among which are computers and mobile phones.
He USB port , therefore, it is a component that aims to connect different devices to each other. A printer, a mouse, a webcam and speakers are some examples of peripherals that can be connected to a USB port, not forgetting the increasingly popular external hard drives and classic memory keys (pendrives).
Although there are several adapters, it is best to use devices that have the USB connector to facilitate the process of connecting and moving them. The USB port can be understood as a entry in which only those artifacts with the appropriate tab can be entered. Just as there are certain models of mouse that can be connected to a USB port, other mouse classes have different characteristics and must be connected to another port (PS / 2 ).
One of the great advantages of the USB port is that it does not require restarting the system to recognize that a peripheral has been connected. In this way, the device in question can be connected and used (plug-and-play ). USB technology also has the ability to detect the computer program that is needed for the device to work, automatically proceeding to its installation. Among the most questioned aspects of the USB port, however, is its reduced bandwidth to transfer data.
It should be noted that there are different USB ports according to the speed transfer they support, being the USB 3.1 The fastest today. Most modern devices have adopted this version, although others, for economic reasons, continue to rely on the previous generation (2.0).
The USB 3.1 port offers a considerable improvement in speed, since surpasses its predecessor almost twenty times allowing transfers up to 10 Gbps (giga bits per second), which is roughly equivalent to passing the contents of two CDs per second from one device to another. This standard, as well as 3.0, which shined at the time for its 5 Gbps speed, is absolutely backward compatible in its original format, characterized by the blue connector.
Backward compatibility is a very important factor in the world of computing and electronics in general, as users often invest large amounts of money to keep up; if companies ignore that reality and launch products incompatible with each other every year, it would be equivalent to forcing their consumers to buy them so as not to be left behind, which would result in the loss of their trust and respect.
But backward compatibility is not always possible , and every now and then it is necessary for companies to adopt new and revolutionary formats to offer their users truly innovative and beneficial products for them. This seems to be the case of USB-C connector , which is based on specification 3.1 but aims to leave behind the large number of connectors in the market , which generates a lot of confusion for consumers.
The USB-C port is characterized by having a small connector, which allows its use on any device. In addition, it is capable of transmitting any type of signal, from data to Energy ; For example, there are laptops that no longer require a special port for the charger, because they take advantage of the USB-C. In the case of mobile phones and tablets, since USB-C supports up to 100W of power , it is possible to load several at once.
